STEAlVl-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 722,272, dated March10, 1903.

Application filed February 28,1902. Serial No. 96,155. (No model.)

To aZZ whom it may concern-.-

Be it known that 1, WILLIAM JAMES BAKER, a subject of the King of GreatBritain, residing at Peasholme House, Scarborough, in the county ofYork, England, have invented new and useful Improvements inSteam-Separators, of which the following is a specification.

This invention consists principally in improvements upon myformer-British patents, No. 5,516, dated March 15, 1895, and No. 15,384,dated June 28, 1897, and has for its object to effect the more completeseparation of oil or water from exhaust or other steam.

In carrying out my former inventions I employ a deflector and severalrows of angleirons placed vertically to intercept the steam charged withgrease or water, the said angleirons acting as bafflers to collect thegrease or water impinging upon them and also as channels for conductingthe separated or collected grease downward to the well or lower part ofthe separator. In my present improvements I employ deflectors fordiverting the course of the steam, and as angle-irons are a cheaparticle of commerce, easily procured, and exactly answering my purpose Icontinue to employ angle-iron baiflers; but they are now arranged insuch manner as to be more effective in the collection and separation ofgrease than as they were arranged according to my former patents. As analternative to the employment of angle-iron bafflers channel-irons ofU-section may be used.

In order to enable this invention to be fully understood, I will proceedto describe the same with reference to the accompanying drawings, inwhich Figure 1 represents in a sectional plan the arrangement of the angle-iron bafflersaccording to my former patents referred to. representsa sectional plan, and Fig. 3 a sectional plan, upon a larger scale, ofthe improved arrangement of angle-iron bafflers. Fig. l represents asectional plan, and Fig. 5 a sectional plan, upon a larger scale, of theimproved arrangement of channel-iron or-U section bafflers. Fig. 6represents a sectional elevation, and Fig. 7 a sectional plan, of arectangular separator constructed according to my improvements, thesteam entering at the top of the apparatus and passing out at Fig. 2 g

the bottom. Figs. Sand 9 are corresponding views of a separatorin whichthe steam enters at the bottom and leaves at the top.

Similar letters refer to similar parts in all the drawings.

Arrows indicate the direction of the currents of steam. I

In Fig. 1 the angle-iron bafliers A A (shown in section) are so arrangedthat the center of each angle in the second row B B is opposite to thespace between two angles in the front row A A, or what is known as thehitand-miss arrangement; but itis quite possible for a certain portionof the steam to pass through several rows without such actual contactwith sufficient surface of the angle-irons as to collect and separate asmuch of the oil or water as maybe desirable. For instance, a largevolume of steam might pass in the direction of the arrows at a; withvery little contact or separation taking place. Now the principal objectof this invention is by means of an improved arrangement of theangle-iron bafflers relatively to one another (as illustrated in Figs. 2and 3, wherein the angleirons are fixed in double rows, the front row AA having its angle turn ed tothe steam-inlet and the second row with'itshollow to the front row, so that the angle-irons of the front row bridgeover the space betweeneach two angle-irons in the second row) to preventthe steam from short-circuiting or passing through without being forcedin its passage to come into contact with both sides of theangle-ironbafflers.

13y means of the above arrangement the steam isffirst driven into theangle of the secondrow of angle-iron bafflers B B and is then reversedin its course, turning back into the angle of the front row A A, so thateach double row compels the steam to pass into the angles of each row,besides reversing the direction and causing contact with both surfacesof thebafflers.

The modification shown in Figs. 4: and 5 acts in a similar manner to thearrangement represented at Figs. 2 and 3, U -sectioned bafders beingsubstituted for angle-irons.

Figs. 6 and 7 represent arectangular separator in which the steam entersat the inlet branch 0 and, passing between the top of the separator andthe deck or partition D D, is led downward at both ends of the separatorby deflectors or baftlers E E until it comes in contact with the greasywater F F, as in my former invention, and then passes between theangle-iron or other bafflers, which may be arranged as above referred towith reference to Figs. 1, 2, or 4, respectively. The overflow forseparated grease and water at H H may be connected with a suitable pumpwhen the separator is required to work with a condenser under a vacuum.The purified steam passes out at the branch G, which may be connecteddirect to a condenser or conducted away by pipes.

In Figs. 8 and 9 a separator is represented which is similar in mostrespects and in action to that already described, except that the steampasses in the reverse direction, entering at C and passing up theinternal pipe 0 until it comes in contact with the partitionplate D D,and then downward below the edges of the deflectors E E, coming incontact with the greasy water, and then passing between angle-iron orother baftlers arranged as previously described, and finally passingupvtrd and over the plate D D to the outlet In order to preventsplashing of the greasy water from the bottom of the separator by aninrush of steam, which water might be thrown up in the form of sprayupon the angle-iron bafilers and carried forward by the current ofsteam, inclined plates (represented at K K, Figs. 6 and 7) are fixed atdistances of, say, about one inch apart across the space occupied by thegreasy water at the bottom of the separator, or the water-space may beclosely packed with short lengths of tube fixed vertically, asrepresented at L L in Figs. 8 and 9. Either of th'ese devices willprevent the water from beingsplashed or driven up in the form otsprayuponthe angle-iron bafiiers.

For a steam drior for separating water from steam, as the steam isgenerally live steam at a high pressure," which requires to be purified,the shell of this apparatus is preferably made in a cylindricalform; butthe angleiron or other bafiilers are arranged in the manner describedand represented.

The double rows of angle-iron orother baffiers described are held inposition by angleirons or stays fixed to the shell of the separator, andas many of these double rows may be placed in each shell as are requiredto fully purify thesteam without causing an undue amount of resistanceor back pressure Having now particularly described and aseertained thenature of my said invention and in .what manner the same is to beperformed, I declare that what I claim is 1. 111 a steam-separator, thecombination with a casing having a steam inlet and outlet, of a seriesof bathe-plates located between said inlet and outlet, said plateshaving each a longitudinally-extending concave side and an oppositelongitudinally-extending convex side, said plates being arranged inrows, the concave sides of the plates of one row being toward theconcave sides of the plates of another row, and the adjacent edges ofthe plates of one of said rows being opposite the concave faces of theplates of the other rows, substantially as described.

2. In a steam-separator, the combination with a casing having a steaminlet and outlet, of a series 9f bathe-plates located between said inletand outlet, said plates having each a concave side and an oppositeconvex side, said plates being arranged in rows, the concave sides ofthe plates of one row being toward the concave sides of the plates ofanother row, and the adjacent edges of the plates of one of said rowsextending into the concave portions of the plates of the other row,substantially as described.

3. In a steam-separator, the combination with a casing having asteam-inlet and a steam-outlet, a series of baffle-plates located insaid casing between said inlet and outlet, a deflector for directing thesteam down toward the bottom of the casing, and a plurality ofstationary devices located in the lower part of the casing to preventthe water contained therein from splashing, substantially as described.-
